When choosing plants, consider first their shape, habit, texture and colouring for the place they will occupy and in relation to each other. For a group of plants, choose a tall specimen to give height (dracaena or schefflera), a climbing variety (philodendron), several bushy varieties (begonia or aglaonema), and a trailing vine to cascade over the edges of the container. Try also for good contrasts of leaf shape and colour, choosing the fresh and subtle green-leaved plants for outstanding specimens in key positions. Use multiple wall brackets rather than the type of bracket that holds a single plant, to allow scope for grouping and massing.
